Bandwidth’s 40-acre headquarters in Raleigh, North Carolina, combines a five-story office building with low-rise buildings for Montessori-based daycare and meetings. Those smaller structures use reclaimed mill lumber and a standing-seam metal roof to give a modern workplace a recognizable rural reference. The specified roof is Petersen’s PAC-CLAD Tite-Loc Plus in Graphite: 24-gauge panels, 16 inches wide, covering 87,000 square feet of the project.
The result is not a rustic imitation of a barn. It is a coordinated campus strategy in which building scale, salvaged material and a concealed-clip metal roof provide a connection to the region’s agricultural and mill history while serving contemporary office and amenity functions.

What the Raleigh campus includes
The project is Bandwidth’s headquarters property in its hometown of Raleigh. The campus is organized around a five-story office building and a group of lower buildings that support daily life and company events. The lower structures house an onsite daycare center and a separate meeting building, giving the campus uses that are more domestic and communal than a conventional office floor plate.
Metal Architecture’s project feature, published July 10, 2025, describes the low-rise buildings as having a streamlined, barn-like profile. That profile establishes the rural reference without copying a historic farm building literally. The daycare was designed by Gensler’s Raleigh-Durham office, according to the feature. The meeting building is separate, allowing event and gathering space to function alongside the childcare program while retaining a consistent architectural language.

Why the low-rise buildings carry the rural identity
The five-story office block gives the headquarters its urban workplace scale. The daycare and meeting buildings sit lower and read more like a collection of outbuildings. Their proportions make the campus approachable at ground level, while the repeated roof geometry ties the different uses together.
This division also helps the campus communicate its program. Visitors can distinguish the main office from the buildings intended for children, meetings and events, yet the materials and roof form prevent the property from feeling like unrelated structures placed on one site.
How reclaimed lumber and metal roofing create the rural reference
The feature identifies lumber salvaged from a 200-year-old mill as a major material choice in the lower buildings. Reusing that timber introduces visible age and irregularity into a new corporate setting. The project does not rely on old-looking finishes alone; it uses material with a documented previous life to connect the campus to regional industrial and rural history.
The roof supplies the counterpoint. Standing-seam metal is associated with agricultural and utility buildings, but the system specified here is a tightly detailed architectural roof. Its long, uninterrupted panels and concealed attachments keep the surfaces visually calm. Paired with reclaimed wood, the roof reads as a contemporary interpretation of a barn rather than a decorative application of rustic imagery.
Material contrast is doing practical work
Wood and metal age differently, so the combination gives the low buildings visual depth. The salvaged lumber carries texture and evidence of use; the Graphite roof provides a consistent plane that can span the buildings’ simple forms. The contrast also helps the campus avoid an overly historic appearance: the timber references the past, while the engineered roof system signals current construction.
The available project descriptions do not provide a life-cycle assessment, maintenance schedule or measured energy performance for the material combination. Those outcomes should not be assumed from the appearance of reclaimed wood or from the use of a standing-seam roof.

Documented roof-panel specifications
Petersen’s project page identifies the roof product as PAC-CLAD Tite-Loc Plus panels in Graphite. The case information records the following project values:
| Item | Documented value |
|---|---|
| Panel system | PAC-CLAD Tite-Loc Plus |
| Finish/color | Graphite |
| Metal thickness | 24 ga |
| Panel width | 16 inches |
| Recorded project quantity | 87,000 square feet |
| Project | Bandwidth Inc. Headquarters, Raleigh, North Carolina |
The 87,000-square-foot figure is the quantity recorded on the manufacturer’s project page; it is not presented as the roof area of one individual building. The available documentation does not state panel lengths, substrate build-up, insulation values, slope, underlayment, attachment spacing or installation dates.
What a concealed floating-clip standing seam does
The Metal Architecture feature reports that the panels use concealed floating clips. A clip is fixed to the supporting structure while the panel is secured to the clip, keeping fasteners out of the exposed roof face. “Floating” refers to the clip’s ability to accommodate movement as the metal heats and cools.
Metal panels expand and contract with temperature changes. A system that allows controlled movement can reduce stress at attachment points and help the roof remain continuous as conditions change. The exact movement range, clip spacing and engineering calculations for this project are not stated in the published descriptions, so those values must come from the project’s approved shop drawings and structural documents.
Why the seam shape matters
The feature also describes 180-degree seams and associates them with structural performance and resistance to wind uplift. That is a source-attributed description, not independent test documentation for this particular installation. Actual performance depends on the complete assembly: panel profile, seam engagement, clips, purlins or deck, fasteners, perimeter details, penetrations and the design wind criteria for the site.
For a construction team, the practical lesson is to treat the seam and clip as part of an engineered roof assembly rather than as a finish selected after the building form is complete. The roof edge, valleys, transitions and penetrations need the same level of coordination as the field panels.

Designing a barn-like profile for contemporary uses
A barn reference can become superficial if it is reduced to a pitched roof and dark siding. At Bandwidth’s campus, the rural cue is supported by the buildings’ functions and scale. Daycare and meeting spaces are housed in low structures that can be read as communal outbuildings, while the office remains the larger, more vertical element.
Daycare considerations
The Montessori-based daycare gives the rural-profile buildings a daily, family-oriented use. The available feature names Gensler’s Raleigh-Durham office as the daycare designers but does not publish classroom areas, occupancy, playground dimensions or licensing specifications. Those operational requirements would govern the interior planning and site design independently of the roof’s appearance.

The separate meeting building extends the outbuilding idea to company gatherings. Its separation from the office can help manage event circulation and allow the headquarters to host visitors without routing every activity through the main workplace. No room capacities, acoustic ratings or event schedules are provided, so the project description supports the building’s role but not detailed operational claims.
Coordination issues a contractor should resolve early
Standing-seam roofs look simple because the field is composed of long lines. The difficult work is concentrated at interfaces. A project with reclaimed timber and multiple low-rise buildings should coordinate those interfaces before fabrication.
- Structure and clip layout: Confirm the supporting deck or framing, clip type, spacing and movement provisions in the approved structural package.
- Roof geometry: Resolve ridges, hips, valleys, eaves and transitions between the office building and lower structures before panel lengths are released.
- Penetrations: Coordinate mechanical, electrical and plumbing penetrations with the standing-seam manufacturer’s details so field cuts do not compromise seams.
- Wood-to-metal interfaces: Detail flashings and drainage where reclaimed lumber meets roof edges or wall assemblies, accounting for variations in salvaged material.
- Water management: Verify underlayment, closures, gutters, downspouts and splash control as one drainage strategy rather than treating the roof panels in isolation.
- Access and sequencing: Protect the Graphite finish during material handling and keep later trades from damaging completed seams or flashings.
What the project says about adaptive material choices
Using lumber salvaged from a 200-year-old mill gives the lower buildings a direct material connection to the past. The project descriptions do not identify the mill, the quantity of timber reused, the grading process or the percentage of the original structure incorporated. Those details matter when evaluating reuse claims, but the documented point is clear: the wood was salvaged and used as part of the campus’s architectural expression.
The metal roof complements that strategy by providing a new, repeatable component over the irregular character of reclaimed wood. This pairing can be useful for other commercial projects seeking regional identity without reproducing historic construction methods. It also illustrates a boundary: a visual reference to rural heritage is not evidence that a building has the same agricultural function, construction technique or environmental performance as a historic barn.

Office-market context: why campus reuse is part of a wider conversation
Building Enclosure reported on July 11, 2025, that more than 15.2 million square feet of office space converted to logistics use in 2023, attributing the figure to Newmark and CoStar. Building Enclosure is the immediate source for that statistic, and the original Newmark or CoStar publication was not available in the reviewed material. The number therefore should be read as a trade-publication report, not as independently verified data here.
That context highlights the value of projects that make a headquarters campus serve several functions rather than treating offices as interchangeable floor area. Bandwidth’s campus combines workplaces with childcare and meeting facilities, and its architecture gives those uses a coherent identity. The project is not evidence that every office campus should adopt a rural style or that a standing-seam roof solves office utilization challenges. It is a specific example of programming, material selection and form being developed together.
How to evaluate a similar standing-seam roof proposal
- Define the architectural intent. Decide whether the roof is carrying a regional reference, a low-maintenance objective, a long-span expression or another clearly stated purpose.
- Separate documented specifications from aspirations. Record the panel system, gauge, width, finish and quantity, then list performance requirements that still need engineering or test documentation.
- Coordinate the complete assembly. Review structure, clips, seams, underlayment, insulation, flashings, drainage and penetrations as a single package.
- Test the details at transitions. Mock up eaves, ridges, valleys, wall interfaces and penetrations before full production, especially where reclaimed materials introduce dimensional variation.
- Plan protection and maintenance. Establish access routes, touch-up rules, inspection points and procedures for replacing damaged panels without compromising adjacent seams.
- Document what is actually delivered. Keep final shop drawings, as-built panel maps, finish information and maintenance instructions with the closeout package.
What is established—and what remains unspecified
The published project information establishes the campus location and scale, the five-story office building, the daycare and meeting buildings, the barn-like profile, the reclaimed mill lumber, and the use of PAC-CLAD Tite-Loc Plus panels in Graphite. It also records 24-gauge metal, 16-inch panel width and 87,000 square feet for the project.
It does not establish a product price, a comparative ranking against other roof systems, independent wind-uplift test results for this installation, energy savings, service life, maintenance cost or a measured sustainability outcome. Those questions require project records, engineering submittals, verified testing or post-occupancy data beyond the descriptions available for this campus.

At Bandwidth’s Raleigh headquarters, the standing-seam roof is more than a weatherproof cap. Its long Graphite surfaces give the low buildings a disciplined profile, while reclaimed mill lumber supplies the tactile evidence of age. The daycare and meeting programs make the outbuilding analogy functional, and the five-story office anchors the composition as a contemporary corporate campus.
The project’s strongest lesson is the value of alignment. Rural character comes from the combination of scale, use, material and roof detailing—not from any single product claim. The documented roof specifications make that design intent buildable, while the limits of the available data show why final performance conclusions must come from the project’s own engineering and maintenance records.
